maybe you are a little boring to talk about cameras, but i would need some suggestions.
i´ve always used firewire or usb cameras (mainly because i´ve used only laptops for the performances) and i´ve noticed that there is an appreciable latency in the video signal even using a simple tracking chain (2 or 3 render passes), this is not really important in the most of the situations, but in others it kills the illusion in a performance.
Making some research i´ve found some information explaining that the lowest latency way to capture live video, is using an analog camera and a frame grabber, it has bigger resolution (PAL) and also the analog video cables are cheaper (& longer) than firewire or usb ones.
There is also a very useful documentation about tracking here (thanks! wirmachenbunt, and Frank):
Could someone confirm it? or tell me the best setup to work with very, very low latency?
I´m thinking to buy the Falcon PCI card and a used Hitachi industrial monochrome EIA camera for my setup (i hope enough NIR sensitive, i didn´t find any info about the spectral response), instead of firewire solution, mostly after the nightmare with the Imaging Source drivers.
Anyone with experience with this capture card and vvvv? i saw that there is a wdm driver.
i read also that EyeCon (Frieder Weiss) is developed mostly for this card with some “special” drivers, i think for better response, lower latency ¿?.
btw, is there any difference in latency/performance between the PCI and PCIe model?
The camera works at 60fps interlaced mode, i think with a deinterlace freeframe plugin would be enough to be used for computer vision, isn´t it?
Maybe these questions are obvious, but i´m a post analog video guy ;)
Sorry for the questionnaire, thanks in advance.
